Hi There,

Im trying to install guix 1.3.0 latest version but i couldnt proceed 
after this step mentioned here:

It will give error provided in the attachment.

Note(1): Im following the manual installation method , using MBR method 
of installation dos/xvda, xvda1 40GiB ext4 , xvda2 8GiB swap. Inside Xen VM

Note(2): Used exact same steps with Guix 1.2.0 and went through smoothly.
